| How is the rotational velocity of a Kerr Black Hole measured? Posted: 19 Jun 2016 06:15 AM PDT Is there even a way to measure it to a substantial degree of certainty? Are there other ways to measure it than through the gravitational lensing effect on photons? [link] [comments]  |
| Is it possible to have potential energy but be at 0 potential? Posted: 19 Jun 2016 06:13 AM PDT Imagine we have a positive test charge in between 2 oppositely charged spheres. At the point exactly between them, the potential should be 0. However I think that the test charge would still move (towards the negative one and away from the positive), meaning it must have potential energy. How is it possible for it to have some potential energy yet be at 0 potential, defined as potential energy per unit charge? There must be a flaw somewhere but I'm not sure which bit of my thinking is wrong [link] [comments]  |

| Why does thermal radiation exist if atoms are neutral in charge? Posted: 18 Jun 2016 11:23 PM PDT My understanding of thermal radiation is that every atom acts as a tiny oscillating dipole because it contains an oscillating charge. But wouldn't the magnetic fields created by the nucleus cancel out the fields produced by the electrons? [link] [comments]  |
| Posted: 18 Jun 2016 11:09 PM PDT I have been thinking about this for a while, and I'm pretty curious. I love thinking about Planck Lengths, and stuff. Pretty cool stuff! [link] [comments]  |

| Posted: 18 Jun 2016 08:10 PM PDT From Max Born, the postulation is that the square of the amplitude of a wavefunction gives the probability of a particle existing at a position x at a time t, but from a mathematical point of view can we not consider wavefunctions as simply probability density functions and apply integration to determine the probability of a particle existing within set parameters? Is that impossible to do, or more difficult? Why do we use the square of the amplitude? [link] [comments]  |

| What exactly causes hypoglycemia / diabetic coma in diabetic patients? Posted: 18 Jun 2016 01:43 PM PDT Aside from too much antiglycemics / insulin relative to blood glucose levels. I have seen many diabetic patients that do not follow a med regimine at all yet will drop to dangerously low levels. What causes this? Can a non diabetic person experience a "diabetic coma"? If not, why? Thanks! [link] [comments]  |
| Why isn't Hawking Radiation Power proportional to the Surface Area of Event Horizon of a Black Hole? Posted: 19 Jun 2016 03:25 AM PDT Why does a solar mass blackhole only radiate ~10-29 Watts while a 105 kg blackhole emanates ~1021 Watts. [link] [comments]  |
| If the Earth's atmosphere were 20% thicker would that be a boon or a burden for fixed-wing aircraft? Posted: 18 Jun 2016 11:15 AM PDT All other things being equal, if you took a modern jet or turboprop plane and plopped it into an atmosphere with the same gas composition but 20% thicker would that make the unmodified lifting surfaces more efficient? Less efficient? About the same? Setting aside any effects that thicker air would have on the efficiency of the combustion process in the engines (let's just say we can provide the same amount of power), would the plane have to work harder to push through the denser air and/or overcome drag?

| Why has Titan retained its atmosphere? Posted: 18 Jun 2016 10:56 AM PDT At 0.14g and without its own magnetosphere why hasn't Titan been stripped of its atmosphere by the solar winds, jeans escape, and other similar atmospheric escape mechanisms? [link] [comments]  |
| Posted: 18 Jun 2016 11:10 PM PDT I have a rope and I pull it, of course it will break at it's weakest point. Now somehow I made a perfect rope (at atomic level), it's the same (hardness, density,...) everywhere and I pull it again. What will happen? It's unbreakable, or get splitted into atom, or just simply breaks at random places? [link] [comments]  |
| Can the nuclear force hold two protons together without violating the Pauli exclusion principle? Posted: 18 Jun 2016 10:46 AM PDT So since the nuclear force has a spin dependent component the force between two protons with anti-aligned spins should be too low to hold them together. So that means that the only way for two protons to be bound to each other would be if their spins were aligned, but wouldn't this violate the Pauli exclusion principle as they'll both be in the same quantum state? Is it even possible for two protons to be bound together, or is it just the neutron(s) and proton(s) being bound together to keep a nucleus together? [link] [comments]  |
| What exactly is p in E^2 = (m^2)(c^2) + (pc)^2? Posted: 18 Jun 2016 07:00 PM PDT I know it means momentum, but what momentum exactly? The momentum of one or both of the colliding objects? I saw "change in momentum in the system" somewhere, but in what way and to what extent does the momentum change? Can it, or is p always 0? [link] [comments]  |
